PADS Professional

An integrated solution without compromise for any PCB design challenge

PADS Professional Premium is the affordable, intelligent, and integrated PCB design and verification flow tailored by Siemens for hardware engineers and small workgroups using the Xpedition technology, that incorporates design data management, component research, component sourcing knowledge, and extended collaboration for PCB engineering projects.

With PADS Professional Premium, design teams have everything they need to bring even complex projects into production quickly and without errors, for the most demanding challenges of today’s market.

Why choose PADS Professional Premium for PCB Design?

Real-time Component Sourcing

The Supply Chain application empowers engineers with real-time component sourcing data provided by Siemens to make more informed part decisions when cost-of-change is lowest.

Seamless Cloud Collaboration

Connect for PADS Professional empowers you to go beyond your desktop work environment and seamlessly collaborate teammates worldwide via design data management, BOM management, and team sharing, visualization, and markup.

Part Search & Creation

The PartQuest Portal application provides the building blocks to design new products fast: a searchable catalog of 8M parts & ECAD library model content that can be downloaded, & the ability to create custom symbols & footprints.

Design Without Compromise

With PADS Professional Premium, your tools won’t limit your ability to design. Unlike other systems that advertise “price conscious” tools, the PADS Professional Premium flow is infused with vibrant, dynamic technology for a complete and comprehensive solution.

The same technological foundation as Xpedition

PADS Professional Premium is built on the same technology foundation as that used to design the world’s most complex PCBs. PCB designers and hardware engineers who do it all – operating independently or in small workgroups – will find PADS Professional Premium to be the perfect solution.

It has everything needed to design complex PCBs within a tightly integrated flow:

  • Hierarchical schematic and table-based design creation with intelligent part selection and verification
  • Logical and physical variant management
  • Rigid-flex design capabilities
  • FPGA I/O optimization to reduce signal length and layer count and eliminate costly re-spins
  • Unified constraint definitions and management across the flow
  • Easy design reuse of schematic, constraints and layout
  • Board-level thermal analysis
  • Best-in-class PCB layout featuring:
    • A single layout environment
    • Concurrent 2D and 3D physical design
    • Correct-by-construction approach to placement, plane design and routing
    • Hierarchical component planning and placement
    • The industry’s most powerful inter- active routing environment for large busses as well as single-ended and differential pair nets
    • Ground-breaking sketch routing
    • Advanced fabrication design including HDI, RF, flex circuitry and embedded components
  • Component information and library management
  • Starter library with over 11,000 part numbers and IPC-7351B compliant.
  • Analog/mixed signal SPICE simulation
  • PCB documentation and manufacturing outputs
  • Design archive management and design review

Top 4 reasons why customers chose PADS Professional with us

We have many PADS Professional customers throughout Europe who are happy to work in partnership with Cadlog and Siemens. Following a survey, we identified the top 4 reasons why they chose PADS Professional.

Enter the Siemens ecosystem

Adopting PADS Professional for PCB Design, you enter the ecosystems of two well-recognized players of the industry: Siemens and Cadlog. PADS Professional is strictly integrated with all key Siemens’ technologies for electronics, like Valor NPI, HyperLynx, Simcenter Flotherm XT, Solid Edge, and Process Preparation.

Tailored and localized service

If you have a question about how to improve your design and use the tools in the best way, you can refer to one of the well-known professionals, who are part of an international professional network, speak your language and have the knowledge to offer answers that are tailored to each customer’s needs.

Top-class technology at your disposal

With PADS Professional you can design, validate, and manufacture complex PCBs because it is the cutting-edge solution that delivers Xpedition technology to Small-Medium Businesses and to engineering professionals who work outside a corporate CAD environment.

Digital Twin made easier

PADS Professional allows design teams to have fewer design spins with Virtual Prototyping including SI, PI, Thermal, DFM, and 3D validation. The Digital Twin of the product allows you to anticipate all analyses and verifications at the initial stages of the project.

ECAD MCAD Co-Design with PADS Professional

PADS Professional provides powerful ECAD/MCAD CoDesign functionality that is easy to use and saves significant time. It allows the mechanical engineer and the electrical engineer to work in their familiar authoring tools, while also allowing the easy sharing of data between those tool environments. PADS Professional MCAD Collaborator works with any MCAD tool that supports the industry-standard IDX interface.

The flow is very simple and effective. The Mechanical Engineer starts the design by creating the board outline, inserting mounting holes, and placing critical components, such as connectors, heat sinks, and other large mechanical structures. In the meantime, the Electrical Engineer is working on the schematic. When the Electrical Engineer is ready to start placing components, he opens the 3D environment in PADS Professional and activates the MCAD Co-Design feature. The Electrical Engineer can now begin placing components in the familiar 2D environment. Rooms of components that were grouped together in the schematic can be dragged together onto the PCB.

Opening a 3D tab inside of PADS Professional will show the board in full 3D.  Components that were used in previous designs will already have 3D models assigned to them. STEP models may be downloaded from a vendor’s website and are also available from numerous free content providers. In addition, the Mechanical Engineer provides STEP models, created within his MCAD environment, for all mechanical components and piece parts like screws, stand-offs, brackets, and heatsinks.

How schematic AMS simulation in PADS Professional can ensure proper design intent

By simulating your designs before layout or manufacturing, you can ensure that your circuitry is behaving as intended, while also eliminating costly performance issues later on. In this example, we will design and simulate an oscillator circuit with SPICE and VHDL-AMS models. We will then explore how to utilize the fully integrated features of AMS to simulate pre-existing schematic designs.
